Abstract

Disclosed is a structure for finely adjusting the distance between image output portions constituted by a plurality of panels or modules of a display apparatus. The display apparatus includes a display panel including a first panel module and a second panel module arranged in a vertical plane for outputting images forward, a support frame disposed at the rear of the display panel for supporting the display panel, and a control unit disposed at the rear of the display panel for controlling the outputting the images from the display panel. The display apparatus further includes a connection unit, a receiving unit, and an adjustment unit for finely adjusting the distance between the display modules. In addition, the display apparatus further includes a recess part and a protrusion part, which are movably coupled to each other for circuit connection, in order to enable fine adjustment of the distance between the display panel modules of the display panel.

First claim

What is claimed is:

1 . A display apparatus comprising:
a display panel; a support frame disposed at a rear of the display panel and configured to support the display panel; a connection unit disposed at a first side of the support frame in a first direction and configured to protrude in the first direction; a receiving unit disposed at a second side of the support frame in a second direction opposite the first direction and shaped to comprise a receiving hole depressed in the first direction; and an adjustment unit configured to be inserted into the receiving unit in a third direction perpendicular to the first direction, wherein, on an assumption that the connection unit is inserted into the receiving hole, the adjustment unit is configured to cause the connection unit inserted in the receiving hole to move along the receiving hole as the adjustment unit moves in the third direction in a state of being in contact with the connection unit.

2 . The display apparatus according to claim 1 , wherein the display apparatus further comprises:
a plurality of connection units arranged along the first side of the support frame; and a plurality of receiving units arranged along the second side of the support frame and disposed at positions along the second side corresponding to positions of the plurality of connection units on the first side.

3 . The display apparatus according to claim 1 , wherein:
the adjustment unit comprises a first inclined surface that faces a direction between a direction in which the adjustment unit is inserted and the first direction, and the connection unit comprises a corresponding second inclined surface configured to contact the first inclined surface on an assumption that the connection unit is inserted into the receiving hole.

4 . The display apparatus according to claim 1 , wherein the adjustment unit comprises a tapered contact part at an end in a direction in which the adjustment unit is inserted, and
the connection unit comprises an inclined surface that slides relative to the contact part as the adjustment unit moves in the third direction on an assumption that the connection unit is inserted into the receiving hole.

5 . The display apparatus according to claim 4 , wherein the connection unit comprises an adjustment correspondence part configured to contact the contact part on an assumption that the connection unit is inserted into the receiving hole, the adjustment correspondence part comprising a first inclined surface and an opposite second inclined surface at a recessed portion of a side of the connection unit.

6 . The display apparatus according to claim 1 , further comprising a guide unit configured to guide movement of the connection unit in the first and second direction.

7 . The display apparatus according to claim 6 , further comprising a catching unit disposed perpendicular to the first direction and configured to fix a position of the connection unit with respect to the guide unit.

8 . The display apparatus according to claim 7 , wherein the connection unit comprises a main groove extending in the first and second direction configured to guide the catching unit.

9 . The display apparatus according to claim 7 , wherein the connection unit comprises:
a first catching recess configured to engage with the catching unit such that the connection unit is fixed at a first position with respect to the guide unit; and a second catching recess configured to engage with the catching unit such that the connection unit is fixed at a second position with respect to the guide unit, wherein the connection unit protrudes further in the first direction from the guide unit at the first position than at the second position.

10 . The display apparatus according to claim 7 , wherein the catching unit comprises:
a catching body supported by the guide unit; a catching end part configured to contact the connection unit; and an elastic member configured to bias the catching end part away from the catching body.

11 . A display apparatus comprising two display modules each comprising a display panel and a support frame disposed at a rear of the corresponding display panel for supporting the display panel, wherein:
a first display module of the two display modules comprises a connection unit disposed at a first side of a first support frame of the first display module in a first direction and configured to protrude in the first direction; a second display module of the two display modules comprises:
a receiving unit disposed at a second side of a second support frame of the second display module in a second direction opposite the first direction and shaped to comprise a receiving hole configured to receive the connection unit in the first direction; and
an adjustment unit configured to be inserted into the receiving unit in a third direction perpendicular to the first direction, and the adjustment unit is configured to cause the connection unit to move along the receiving hole as the adjustment unit moves in the third direction in a state of being in contact with the connection unit.

12 . A display apparatus comprising:
a display panel comprising a first panel module and an adjacent a second panel module arranged in an imaginary vertical plane; a control unit disposed at a rear of the display panel and configured to control the display panel to display information; a first recess part fixed to one of the control unit or the first panel module; and a first protrusion part fixed to the other of the control unit or the first panel module, wherein the first protrusion part is configured to be inserted into the first recess part to electrically couple the control unit and the first panel module, and wherein the first recess part is configured to allow movement of the first panel module relative to the control unit in the vertical plane while the first protrusion part is inserted into the first recess part.

13 . The display apparatus according to claim 12 , further comprising:
a second recess part fixed to one of the control unit or the second panel module; and a second protrusion part fixed to the other of the control unit or the second panel module, wherein the second protrusion part is configured to be inserted into the second recess part to electrically couple the control unit and the second panel module, and wherein the second recess part is configured to allow movement of the second panel module relative to the control unit in the vertical plane while the second protrusion part is inserted into the second recess part.

14 . The display apparatus according to claim 13 , wherein:
the first protrusion part protrudes from a rear surface of the first panel module; the second protrusion part protrudes from a rear surface of the second panel module; and the first recess part and the second recess part are disposed at a front surface of the control unit.

15 . The display apparatus according to claim 12 , further comprising:
a support frame disposed at a rear of the display panel and configured to support the display panel, wherein the support frame comprises an opening in which at least the first recess part or the first protrusion part is disposed.

16 . The display apparatus according to claim 12 , wherein the first recess part is further configured to allow movement of the first panel module in a first direction in which the first panel module and the second panel module are arranged.

17 . The display apparatus according to claim 16 , wherein the first recess part is further configured t
